go

\ \ [OE] Go is an ancient verb, traceable back to a prehistoric Indo-European base *ghēi- or *ghē-. This seems to have been relatively unproductive outside the Germanic languages (Sanskrit hā-, hī- ‘leave’ and Greek kikhánō ‘reach’ may be descendants of it), but it has provided the basic word for ‘move along, proceed’ in all the Germanic languages, including German gehen, Dutch gaan, Swedish gā, Danish gaa, and English go. In Old and Middle English its past tense was ēode, later yode, a word of uncertain origin, but from about 1500 this was replaced by went, originally the past tense of wend.
